regexp newbi prob...

well i guess for u javascript pro's this is too simple...
the thing is this: i have an input type text in my form.
i need a way to verifay that the data in that text filed is just numbers.
Using the isNaN, will work but i need to use regExp....
now, i tried to do something like this:

if (document.myForm.Number.value.search(/[^0-9]) != -1)...

now in this way i get -1 if the value is just numbers. any other cobination of letters or numbers and letters will give a result different than -1.
now, this is just fine exept for one case where the value is empty. in this case i get the result of -1
so insted of having -1 only in case the value is numbers (and only numbers) i get the -1 result in two cases, one, when the value is numbers and second when the value is empty...
in order to solve this i currently check the value to see if its empty, but that makes some of the conditions in my script waaay too long and complicated...
there should be a way to create a regexp that will give one result when the value is only number and a different result in any other case (including a case where the value is empty).
any one??

thnx in advanced.

Well, first of all you are posting in the wrong forum, but I will answer your question anyway. Instead of using

try using

That regex should tell you if any characters in the string are anything other than 0 thru 9, including an empty string I would think. If anything in the string is other than 0-9 it will return -1. I did not test this, but it *should* work.
